Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

Chapter 2. Getting Started

2.1 INTRODUCTION

The Microchip EVB-USB5816 Evaluation Kit is designed for flexible configuration solu-

tions. It can be configured via default internal register settings, via a downloadable

external firmware to an onboard SPI Flash (OTP memory), via SMBus, or via the

onboard configuration switches. When configured with the default internal register set-

tings, the device operates as a USB 3.1 Gen1 hub with one upstream Gen1 port, five

downstream Gen1 ports, and one downstream USB 2.0 port, with Microchip’s standard

VID/PID/DID settings.

Microchip provides a comprehensive software programming tool, MPLAB® Connect

Configurator (MPLABCC), for configuring EVB-USB5816 functions, registers, and OTP

memory. EVB-USB5816 requires MPLABCC version 2.1.0 or greater.

For additional information on the MPLABCC programming tool, refer to Software

Libraries within the Microchip EVB-USB5816 product page at

www.microchip.com/USB5816.

2.2 KIT CONTENTS

The EVB-USB5816 Evaluation Kit includes the basic equipment necessary for evalua-

tion. The items included in the kit are:

• EVB-USB5816 Evaluation Board

• Type-A to Type-B USB cable

2.3 QUICK START

Perform the following steps to quickly start using the board:

1. Connect a 12V power supply to the barrel connector (J4) or the terminal block

(J3) on the EVB-USB5816.

2. Using a Type-A to Type-B USB cable, connect the EVB-USB5816 to a USB host

via the upstream “Port 0” USB Type-B receptacle (J7).

3. Devices may now be connected to any of the downstream ports to enumerate

and use those devices with the USB host.

4. To perform additional configuration or evaluate specific features, launch the

MPLABCC software on your USB host or manipulate the included hardware con-

figuration options detailed in the next sections.

Chapter 3. Hardware Configuration

3.1 HARDWARE CONFIGURATION OPTIONS

Figure 3-1 shows the top view of the EVB-USB5816.

FIGURE 3-1: EVB-USB5816 REV B (TOP VIEW)

3.1.1 Configuration

3.1.1.1 EXTERNAL SPI FLASH

Upon power-up, the EVB-USB5816 first searches an external SPI Flash device and a

valid signature in the Firmware image. If a valid firmware image is found, the code exe-

cution is initiated from the external SPI Flash device.

To enable operation from the SPI device, install shunts to pins 1 and 2 of J6. When code

is executing from an SPI ROM device, a blue LED “SPI-ACTIVE” (D8) illuminates.

Note 1: CFG_BC and CFG_Non-Rem options are deselected when the SPI

shunt is installed on J6. When operating in SPI mode, all configuration is

handled by the code executing from the SPI ROM device.

2: If the SPI Flash is not properly programmed or has an invalid signature,

the USB5816 reverts to internal defaults even if the SPI ROM is selected.

EVB-USB5816 Evaluation Kit User’s Guide

DS50002948A-page 16  2020 Microchip Technology Inc.

3.1.1.2 SMBUS

If an SPI Flash device is not found, the firmware checks if SMBus is enabled.

To select SMBus configuration, select OPTION2 from the CFG_STRAP header, shunt

pins 1-2 of J6. The SMBus signals may be accessed at J8, where pin 1 is the clock and

pin 3 is data (pin 2 is ground).

If configuration OPTION2 is selected, and SMBus is enabled (i.e., SMBusclock and

data are pulled up), the EVB-USB5816 waits indefinitely for data from the SMBus inter-

face and will not enumerate to the USB host until the special USB Attach command is

sent.

See the AN2316 Configuration Options for the USB58xx and USB59xx for additional

details.

3.1.1.3 INTERNAL DEFAULT CONFIGURATIONS WITH STRAPPING OPTIONS

When the EVB-USB5816 does not detect a valid SPI Flash image and does not look

for SMBus configuration upon power-up, the EVB-USB5816 uses internal default reg-

ister settings. It also sets the Vendor ID, Product ID, Language ID, and Device ID, and

additional settings from the internal ROM code.

If configuration is not done through SPI or SMBus, additional configuration is available

through two functions: CFG_BC_EN and CFG_NON-REM. The controls are config-

ured by selecting one of the six resistor values for each pin. The EVB-USB5816

demonstrates two of the six possible resistor values for each of CFG_BC_EN and

CFG_NON-REM. These straps are sensed by the EVB-USB5816 device at power-on

to determine the resultant configuration of the device.

To select the CFG_BC_EN and CFG_NON-REM modes, switches must be set on SW3

and SW4.

To use the battery charging strap options or the NON_REM strap options, refer to the

strap select table on schematic page 2. (see Figure A-2.)

3.1.2 Power Source – Self Powered

The EVB-USB5816 only supports self-powered operation. Power is supplied through

one +12.0V regulated external power supply. The power supply is connected to the

2.5 mm connector J1 on the board. Alternatively, an external voltage can be supplied

to the screw terminal “12V” (J2). The +12.0V feeds a 15A regulator that outputs +5.2V

(nominal) across the board and also supplies the +3.3V regulator and the 1.2V regula-

tor.

3.1.3 Downstream Port Power Control

USB power to the four downstream ports is controlled via port power controllers with

auto-discharge functionality. All downstream ports support BC 1.2 battery charging.

The downstream USB Type-C® port is capable of up to 3A of current at 5V. The remain-

ing five downstream USB Type-A ports are capable of up to 2.1A at 5V.

CAUTION

The supplied 12.0V external power supply cannot support simultaneous battery charging on

all downstream ports. Use a higher power supply if the required test use case exceeds the

power capability of the supply. Failure to heed to this warning could result in damage to the

12.0V external power supply.

Hardware Configuration

 2020 Microchip Technology Inc. DS50002948A-page 17

3.1.4 USB Type-C® Port

The EVB-USB5816 has a single USB3.1 Gen 1 PHY for Type-C support. This elimi-

nates the need for an external multiplexer. The EVB-USB5816 also features integrated

Type-C control signal (CC) detection to determine when and in what orientation a USB

Type-C® attach has been made. It powers only the USB3.1 Gen 1 PHY needed for USB

communication. To reduce power, the EVB-USB5816 powers down unused USB3.1

Gen 1 PHYs. In the case where no USB Type-C attach is detected, the USB3.1 Gen 1

PHY associated with that port is powered down.
